How do you attach a workflow to a template

[Liam Superville]

Im working within confluence data center, and would like to attach a workflow to a template. 

{workflow:name=PCCB Workflow|label=pccb}
{state:Submitted|colour=#4A6785|updated=In Review}
{state}
{state:In Review|approved=Ready for Presentation|colour=#00B8D9|taskable=true}
{approval:Presentation Approval|user=dn354f, zt427f,yc887e}
{state}
{state:Ready for Presentation|colour=#ffab00|taskable=true|updated=In Voting}
{state}
{state:In Voting|approved=Approved|colour=#0052CC|rejected=Disapproved|taskable=true}
{approval:Voting Approval|approvelabel=Approved/No Impact|rejectlabel=Disapproved}
{state}
{state:Disapproved|colour=#FF0000|submit=In Review}
{state}
{state:Approved|final=true|hideselection=true|taskable=true}
{state}
{trigger:labeladded|label=pccb}
{set-state:In Review}
{trigger}
{workflow}

Given what im working with, I have tried to create a trigger, as just making a page with pccb label doesnt apply the workflow. But neither works, im at my wits end on how to automate this process.
